Orationes

Familiam tuam, quaesumus, Domine, continua pietate custodi; ut quae in sola spe gratiae caelestis innititur, tua semper protectione muniatur.

"Guard your household, we ask, O Lord, with continual goodness; that they who rely on the hope of heavenly grace alone may always be defended by your protection."

Remarks:
*Note that there is a piety proper to God. We are expected to be pious in his regard, but he is pious in our regard. Deux prior dilexit nos.
*There is great balance between the opening imperative and the closing clause of result: continua-semper; pietate-protectione; custodi-muniatur.
*We are said to depend not on grace, but on the hope of grace. Our position is weak indeed. That is why we are in such need of God's constant care and protection.
